Description

Technical Field

[0001] This invention relates to the technical field of assembly and testing, and in particular to an interlocking floating mechanism. Background Technology

[0002] Currently, a complete product often requires assembly to be presented to us. The connection methods between two assembled products mainly include riveting, threaded connection, welding, hinged connection, and socket connection. With the continuous development and progress of technology, the control of product precision and quality is becoming increasingly stringent. The demand for thinner, smaller, more integrated, and more precise electronic products is growing. During the testing and assembly process, high-precision positioning and motion modules are needed to control the correct positional relationship between the two products before connection, so as to meet the assembly precision and improve product quality.

[0003] In existing technologies, the positioning of two products before assembly is mainly achieved through the use of pins and guide sleeves. However, pins and guide sleeves can introduce positioning errors due to processing and assembly. For products with high positioning difficulty and high mating precision requirements, such as rigid-flex boards, pins and guide sleeves cannot effectively achieve high-precision positioning and assembly. Furthermore, traditional equipment can only assemble one set of products at a time, resulting in low production efficiency. In various material assembly, mating, and testing environments, especially in automated production line assembly and testing industries, the current industry demands variable and inconsistent plug angles, generally requiring multi-angle floating mating for easier assembly or testing. However, existing mating structures are relatively simple and have limited functionality, relying on a single-axis spring as the floating structure, with the floating range defined by the gap in the screw through-hole. Existing floating mechanisms have two significant drawbacks: unidirectional movement, allowing only slight floating in a single direction, along the radial direction of the spring through spring deformation; and a small tolerance range, with circumferential floating limited to screw through-holes or even smaller areas.

[0004] For example, Chinese patent CN213765906U discloses a motor quick-change device based on a robotic arm. Before docking, under the action of a spring, the upper half of the internal gear ring meshes with the upper external gear. The robotic arm grips a flexible clamping structure, moving the quick-change module directly above the reducer. Then, it moves downwards to insert the guide sleeve into the positioning sleeve for axial positioning, while the positioning pin inserts into the positioning groove for circumferential positioning, achieving precise docking of the guide components. However, it can only float slightly in a single direction, floating radially along the spring through spring deformation. Therefore, it is necessary to provide a docking floating mechanism with a compact structure, multiple floating directions, and multi-angle docking. A more diversified floating direction improves the docking success rate, reduces unnecessary material damage, saves material costs, and increases work efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an interlocking floating mechanism with a compact structure, multiple floating directions, and the ability to interlock at multiple angles. The more diversified floating directions are conducive to improving the success rate of interlocking, reducing unnecessary material damage, saving material costs, and improving work efficiency.

[0006] The technical solution adopted by this utility model is as follows: This utility model includes a fixed plate, with the length of the fixed plate as the X-axis direction and the width of the fixed plate as the Y-axis direction. The fixed plate is connected to a base, the base is connected to a floating platform, and the floating platform is connected to a mounting plate. The floating platform has a first through hole along the Z-axis direction, and the base has a second through hole along the X-axis direction and a third through hole along the Y-axis direction. Ball-head plungers are provided in the first through hole, the second through hole, and the third through hole. The ball-head plungers float in cooperation with the base and the floating platform.

[0007] As can be seen from the above scheme, this application, as a floating mechanism, uses an external drive mechanism to install fixed grippers or mating connectors. During docking or mating operations, the floating assembly can complete multi-angle floating by extending and retracting within the gap, thereby completing the mating or assembly operation. Through the use of this mechanism, multi-angle mating or assembly operations are made more tolerant of floating errors, increasing the success rate of operations, reducing unnecessary material damage, saving material costs, improving work efficiency, and optimizing space utilization. The structure is compact and performs better.

[0008] In a preferred embodiment, the base is a cuboid structure with a bottom opening, and the floating platform is an inverted T-shaped structure with its longitudinal portion moving within a deep groove in the base.

[0009] In a preferred embodiment, both the second through hole and the third through hole penetrate the side wall of the base, a floating gap is provided between the outer wall of the longitudinal portion of the floating platform and the interior of the base, a floating gap is provided between the top of the longitudinal portion of the floating platform and the top interior of the base, and a floating gap is provided between the bottom of the base and the floating platform.

[0010] In a preferred embodiment, the top of the base has a mounting hole along the Z-axis, and the mounting hole is connected to the floating platform by a height-equalizing screw.

[0011] In a preferred embodiment, the ball-head plunger of the first through hole mates with the inner wall of the base, and the ball-head plungers of the second through hole and the third through hole both mate with the outer wall of the floating platform.

[0012] A preferred embodiment is that the fixing plate, the base, the floating platform, and the mounting plate are arranged sequentially from top to bottom to form an I-shaped structure. Attached Figure Description

[0014] like Figure 1 As shown, in this embodiment, the present invention includes a fixed plate 1, with the length of the fixed plate 1 as the X-axis direction and the width of the fixed plate 1 as the Y-axis direction. The fixed plate 1 is connected to a base 2, the base 2 is connected to a floating platform 3, and the floating platform 3 is connected to a mounting plate 4. The floating platform 3 has a first through hole 5 along the Z-axis direction, and the base 2 has a second through hole 6 along the X-axis direction and a third through hole 7 along the Y-axis direction. Each of the first through hole 5, the second through hole 6, and the third through hole 7 is provided with a ball-head plunger 8, which floats in cooperation with the base 2 and the floating platform 3.

[0015] The fixed plate 1 is fixed to the equipment robot or running mechanism. The base 2 retains a floating gap and space through the ball plunger 8. The mounting plate 4 is fixed on the floating platform 3. The other half of the mounting plate 4 is fixed with a clamp or a mating connector. When the mating plug or clamp fixed on the mounting plate 4 needs to float during mating assembly or mating operations, it can float at multiple angles through the extension and retraction of the ball plunger 8 in the gap between the base 2 and the floating platform 3, realizing floating in front, back, left, right, up and down, and then completing the mating or assembly operations.

[0016] like Figure 1 As shown, in this embodiment, the base 2 is a cuboid structure with a bottom opening, and the floating platform 3 is an inverted T-shaped structure. The longitudinal part of the floating platform 3 moves within the deep groove of the base 2 to ensure the compactness of the structure.

[0017] like Figure 1 As shown, in this embodiment, both the second through hole 6 and the third through hole 7 penetrate the side wall of the base 2. A floating gap is provided between the longitudinal outer wall of the floating platform 3 and the interior of the base 2, a floating gap is provided between the top of the longitudinal portion of the floating platform 3 and the top interior of the base 2, and a floating gap is provided between the bottom of the base 2 and the floating platform 3. When the mating plug or gripper fixed by the mounting plate 4 needs to float during mating assembly or insertion operations, it can achieve multi-angle floating by the extension and retraction of the ball-head plunger 8 within the gap between the base 2 and the floating platform 3, realizing floating in all directions (front, back, left, right, up, and down), thereby completing the insertion or assembly operation.

[0018] like Figure 1 As shown, in this embodiment, the top of the base 2 has a mounting hole 9 along the Z-axis, and the mounting hole 9 is connected to the floating platform 3 by a leveling screw 10. The base 2 is fixed to the floating platform 3 by the leveling screw 10.

[0019] like Figure 1 As shown, in this embodiment, the ball-head plunger 8 of the first through hole 5 mates with the inner wall of the base 2, and the ball-head plungers of the second through hole 6 and the third through hole 7 both mate with the outer wall of the floating platform 3. When the mating plug or gripper fixed to the mounting plate 4 is in the mating assembly or insertion operation, if floating assembly is required, it can float at multiple angles through the extension and retraction of the ball-head plunger 8 within the gap between the base 2 and the floating platform 3, achieving floating in all directions (front, back, left, right, up, and down), thereby completing the insertion or assembly operation.

[0020] like Figure 1 As shown, in this embodiment, the fixing plate 1, the base 2, the floating platform 3, and the mounting plate 4 are arranged sequentially from top to bottom to form an I-shaped structure, which helps to improve the overall stability.
